Top US health authorities said on Friday that they had not yet found a ‘causal’ link between Johnson & Johnson’s COVID-19 shot and blood clots, as the EU drug regulator probed possible instances among those who had received the vaccine.
‘At this time, we have not found a causal relationship with vaccination and we are continuing our investigation and assessment of these cases,’ said a statement from the US Food and Drug Administration.
The regulatory agency said it was aware of ‘a few individuals’ in the United States who had suffered clots and low levels of platelets in the blood after receiving J&J’s vaccine.
